Specication of Letters Patent.

To aZil 137mm it may 'concern Be it `known that we, RAYMOND H. CAim and JOHN C. MADDUX, citizens of the United States, residing atKingman, in the county of Mohave and State of Arizona, have invented certain new and useful Improvements in Shock-Absorbers, of which the following is a specification, reference being had to the accompanyingy drawings. f

This invention compreliends certain new and useful improvements in shock absorbers for automobiles and similar vehicles, of the type of devices that are Ain, the, nature of auxiliary springs, designed to add to the easy riding qualities of the car to which they are applied and to thus promote the comfort of the occupants as well as to increase the serviceability of the vehicle.

The invention has for its primary object a simple, durable and eiicie'nt construction of device of this character, which will be composed of few parts that may be very cheaply and easily manufactured and readily assembled and which will not be liable to get out of order. And the invention also aims to generally improve devices of this charac- 'ter so as to render them more useful and commercially desirable.

Vith. the above and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combination of the parts that we shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in Which- Figure 1 is an end elevation of an automobile haviiig our invention applied thereto, the automobile being shown in dotted lines and being of conventional form; Fig. 2 is an enlarged fragmentary view of the device.

Corresponding and like parts are referred to in the following description and designated in all of the views ofthe accompanying drawing by like reference characters.

Referring to the drawing, the numeral l designates one of the springs of an automobile, the saine being connected'to the bodyA of the vehicle in any desired way, and 2 designates thev sub-gacent axle. Each ofthese elements may bewof` any desired construction or design, the lowerino'st leaf of the spring l being coiled at its ends, in the usual manner, to receive the coupling pin or bolt 8.

In carrying out our-invention, we mount upright posts 4 upon the axle 2, said posts .being two in number and spaced laterally from each other. rllieseposts may be secured to the axle in any desired way, being shown in the present instance as provided with Shanks or stems 5 which extend through the axle and are `secured in place by nuts screwed on their lower ends, shoulders being Patented Jury t, i914.

formed at the juncture ofl theinain or body l portions of the posts with the shanks, so as to rest firmly upon the upper edge of the axle, as clearly illustrated in the drawing.v

Angular or inverted L-shaped levers Gare pivotally supported at one extremity, as at 7, on the upper ends of the respective posts 4: and are pivotally connected at their elbows to the ends of the spring l, preferably by the pins or bolts 3. The normally vertical arms of the levers 6 extend downwardly from the spring and are pivotally connected at their lower extremities, as at 8, with link rods 9. These rods 9 extend along the axle, as shown and are joined together at their inner or adjacent ends by means of a contractile coiled spring 10.

From the foregoing description in connection with the accompanying drawing, the operation of our improved shock absorber will be apparent. When a load is imposed upon the body of the vehicle, or when the wheels strike an obstruction in the road, the yielding of the main spring l will manifestly be accompanied by a rocking or tilting movement of the angular leversiG about their fulcriiin points 7 and this movement will obviously stretch or expand the contractile spring l0 whereby this spring will serve as an auxiliary to the main spring and shocks and jars will be effectually absorbed.

It will be seen that we have provided a very simple, durable and efficient construc-- tion of this character, which is composed of very few parts and which parts may be readily applied to any vehicle and assembled together.

While the accompanying drawing illustrates what we believe to be the preferred embodiment of our invention, it is to me understood that the invention is not limited thereto, but that various changes may be made in the construction, arrangements and y proportions of the parts without departing from the scope of the invention, as defined in the' appended claims.

For some makes of cars, the posts 4 are apertured to receive the `radius rods, nuts 4'* screwing thereon, as clearly illustrated in the drawing so as to secure the rods in place. When our invention is applied to the car, the tension of the coil spring 10 will pull the levers 6 nearer together at the bottom in orpost.

Vintacta;

end of said levers and tending to draw the same together.

2: In a vehicle and in combination with the 'body spring and axle thereof, posts connected to the axle, and extending upwardly therefrom, angular levers fulcrumed at one end on the upper end of said posts and ,ivotally connected to the body spring at t lelr elbows, link rods pivotally connected to the other extremity of said levers, and a contractile spring operatively connected to said link rods tending to draw the same together. In testimony whereof we hereunto alix our signatures in the presence of two witnesse's.
